Its hard to argue with what you are saying, however I think you need to consider this years cap reduction/situation as a a one off and something that they didnt forsee happening...
We know the situation with the available cap space today, even after a couple of more obvious cuts and restructures that have already happened.. they dont have a lot to play with and they have some holes to fill in what we expect (hope) is a year that they will be contending for the championship... so I think they need to free up a bit more money for this free agency period...
I'd be ok with restructuring a couple of guys to push a bit of money into the next couple of years.. there might be quite a large increase in the cap next year , so roll the dice whilst JA is still cheap...
